Cork-cutting machine



UNI-TED Sme era fr CORK-cucinino MACHINE.

Specification of Letters Patent No. 22,949, dated February 15, 185,9.

To all whom 'it may concern: p

Be it known that I, GEORGE HAMMER, of thecity of Philadelphia and `State of Pennsylvania, have invented new and useful Improvements in Cork-Cuttin`g Machines; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings and to the figures and letters of reference marked thereon.

My invention relates to that class of machinery for cutting c0rks,1in Vwhich a revolving cylindrical cutter is employed and consists: in an improved arrangement for guiding and feeding the cork, while undergoing the process of cutting.

To enable others skilled in the art to make and use my invention I will now proceed to describe its construction and operation.

On reference to the drawing which forms a part of this specication and in which the same letters of reference allude to similar parts throughout the several views: Figure 1 is a side elevation of my improved cork cutting machine, Fig. 2 is a front elevation, Fig. 3 is af sectional plan of the same, Fig. t is a plan of the cam and its connections for feeding the cutter to its work, and Fig. 5 is a detached view of the table of the lmachine in a reversed position. i

The frame A of the machine is so contrived, as to combine all the bearings for the working parts in one solid casting; B is the cutter, consisting in a hollow cylindrical spindle, which revolves inthe journalboxes a., a, and receives its motion from the driving pulley C on the upright shaft D, by means of a strap E, passing over the pulley F on the cutte Gr is the main driving pulley, receiving its power from any convenient line shafting.

The cutter B is at its upper end provided with a swivel-piece which is confined between collars c and (Z, and has a socket for the reception of an arm Gr on a vertical spindle H. To the opposite end of arm G is further attached a roller I, which, being actuated by the cam K on an upright shaft L, imparts to the cutter a motion on a line with its axis in the direction of the arrow Fig. l) and, by thus depressing it, causes its knife edge to penetrate the cork, resting on the table M below. Vhen however the point e on cam K passes and libera-tes the roller I, the spiralspring I will eleigate the spindle H and with Vit the cutter, allowing time for the feeding .of the cork before their next depressionby the cam. Thevertical shaft L, to which this cam is attached, dcrives its motion from the shaft "D through an intermediate shaft N, by a train ofgearing, consisting of thewheels 1,23, et', which areof suoli relative diameterstas to reduce the velocity of L considerably beflowthat of D.

g' is a flat strip of wood, which, filling a dovetail groove in the table M, is apfpliedas a soft, uninjurious surface to "the knifeedge of the cutter,` after penetrating the cork and separating the cylindrical piece from the waste. In order to guide and securely hold the cork, while undergoing the process of cutting, it is directly in front of the cutter confined between the rollers O and P, the former of which revolves on a stud in the slide Q, which is secured to the table M by the screw z', and arranged to shift in a groove for the purpose of adjustment to the different sizes of cutters, the screw v1 passing through a-'slotted hole in the slide.

R is a hand lever, having its fulcrum on a pin 7c, and to the short arm of which is by means of a stud Z attached the roller P. The slices of cork are always entered between the rollers with the inner or close side of the bark against O, which, with its plate Q is so adjusted to the different sizes of cutters, as always to insure the cutting of the latter close to the edge of the bark on this side, while the roller P on lever R yields to all inequality in the thickness of the same. Both the studs it and Z of the rollers O and P have downward projections 5 and 6, extending through slots in the table M, at the bottom side of which they are actuated (for a purpose hereafter described) by the horizontally sliding wedge S, receiving motion from the screw T, which for this purpose is provided with a crank U. Any vchange in the diameter of cutter requires the adjustment of the slide Q and its roller O for the purpose above described. Thisbeing done, the wedge S is brought to bear against the projection 5 of pin 7L, thus causing its opposite inclined edge to act as a limit to the motion of lever R in the direction im parted by the spring m, whereby the roller P at the occurrence of a thin place in the bark or at the end of each piece is checked from yielding so far as to come in Contact with the cutter, which accident would, without the above `precaution be also very apt iio to occur from undue pressure of the roller against the cork, imparted by the hand of the operator. As a guide to t-he operator in feeding the cork through the machine I employ the pin s, which is attached to an adjustable arm T at the lower side of the table and projects upward through a slot in the latter. This pin s, being placed at the back of the cutter, acts as a stop to the feeding advance of the corl after each operation of the former and is by means of a thumbscrew u in a slort t' of arm T readily adjustable to any variation in the diameter of cutters. The position of sy in relation to the cutter is such, that the action of the latter shall leave but a slight thickness of waste between successive perforations, which partition, after the ascent o-f the cutter will readily yield to the pin s during the feeding of the cork for vthe next operation, while the body of the cork will by the pin sy be effectually checked in its forward motion after each action of the cutter.

Having now described the nature of my invention, I wish it to be understood, that I do not desire to confine myself to the described construction and combination of the parts in every minutia, but

What I claim and desire to secure by Letters Patent, is:

The herein described arrangement of guidingrollers O and P and sliding wedge S or their equivalents in combination with the stop s, the whole being constructed and operating substantially in the manner and for the purpose set forth.
